Kevlar Shoe Sole and Heel

ABSTRACT

A sole for a shoe may include a top surface for the substantially solid sole, a bottom surface being opposed to the top surface, and a peripheral side surface connecting the top surface and the bottom surface. The sole may include Kevlar.

FIELD OF THE INVENTION

The present invention relates to a shoe and more particularly to aKevlar sole and/or heel.

BACKGROUND

Shoes are an important part of today's wardrobe. The shoes keep the feetwarm and relatively dry and prevent sharp objects on the ground fromdamaging the feet of the user of the shoes. While the top and sidesurfaces of the shoes receive little wear, the sole and heel may besubject to significant wear as a result of repeated impact with theground and other hard surfaces such as sidewalks and roadway.

The replacement of the sole and heel may be possible but may damage theappearance of the shoe. Additionally, the replacement of the sole andheel may be not practical due to cost considerations.

It would be an objective of the present invention to provide a sole andheel that provides extended wear, and may provide some armor protectionto the feet of the user.

SUMMARY

A sole for a shoe may include a top surface for the substantially solidsole, a bottom surface being opposed to the top surface, and aperipheral side surface connecting the top surface and the bottomsurface.

The sole may include Kevlar.

The sole may include an adhesive.

The Kevlar may have been formed into a needle felt.

The adhesive may be urethane.

DETAILED DESCRIPTION

A sheet 101 of fiber which may be Kevlar which may be rectangular, oval,circular or any other appropriate shape may be punctured by a singleneedle 103 or a multitude of needles 103 which may have a hook end andwhich may be inserted into the sheet 101 and withdrawn from the sheet101. This process may be repeated a number of times and may be extendedover the entire surface of the sheet 101 or a portion of the surface ofthe sheet 101. The needle 103 will tangle and agitate the fiber whichmay be Kevlar of the sheet 101 in order to form a needle felt in orderto achieve a thick and rugged sheet of Kevlar.

The tangled sheet 101 may be soaked in liquid adhesive which may beurethane adhesive 105 which may be sufficiently liquid to enter thefibers of the sheet 101 and form a substantial solid sheet 101. A liquidurethane hardener may be used with the urethane adhesive 105 to decreasethe thickness of the liquid urethane adhesive which may increase thepenetration of the adhesive into the sheet 101. The tangled sheet 101may be in the form of a sole or heel.

The tangled sheet 101 may be cut to meet size requirements and shaperequirements for a particular shoe.

Adhesive such as rubber adhesive may be added to the top surface of thesheet 101 and the sheet 101 may be clamped to the bottom of the shoe 107for example at mid sole as illustrated in FIG. 9. The adhesive isallowed to cure and dry to attach the sheet 101 of needle fiber whichmay be Kevlar to the shoe 107.

FIG. 2 illustrates a perspective view of the sole 101 of the presentinvention and illustrates the Kevlar felted fiber which has beenobtained by the above process.

The sole 101 may include a top sole surface 121 which may be opposed toa bottom sole surface 123 and which may be connected to a sideperipheral sole surface 125 which may extend around the periphery of thesole 101. The side peripheral sole surface 125 may connect the bottomsole surface 123 and the top sole surface 121.

FIG. 4 illustrates a side view of the sole 101.

The sole 101 may include a top sole surface 121 which may be opposed toa bottom sole surface 123 and which may be connected to a sideperipheral sole surface 125 which may extend around the periphery of thesole 101. The side peripheral sole surface 125 may connect the bottomsole surface 123 and the top sole surface 121.

FIG. 5 illustrates a front view of the sole 101.

The sole 101 may include a top sole surface 121 which may be opposed toa bottom sole surface 123 and which may be connected to a sideperipheral sole surface 125 which may extend around the periphery of thesole 101. The side peripheral sole surface 125 may connect the bottomsole surface 123 and the top sole surface 121.

FIG. 3 illustrates a back view of the sole 101.

The sole 101 may include a top sole surface 121 which may be opposed toa bottom sole surface 123 and which may be connected to a sideperipheral sole surface 125 which may extend around the periphery of thesole 101. The side peripheral sole surface 125 may connect the bottomsole surface 123 and the top sole surface 121.

FIG. 7 illustrates a another side view of the sole 101.

The sole 101 may include a top sole surface 121 which may be opposed toa bottom sole surface 123 and which may be connected to a sideperipheral sole surface 125 which may extend around the periphery of thesole 101. The side peripheral sole surface 125 may connect the bottomsole surface 123 and the top sole surface 121.

FIG. 8 illustrates a perspective view of a heel 130 of the presentinvention which may be formed from Kevlar and adhesive as describedabove.
